What movies of this time period do you like? Here are my top three:
1. The Crossing (Excellent account of the Delaware Crossing by Washington)
2. Last of the Mohicans - 1992 (A lame romance, but gotta love that Fort William Henry Massacre Scene)
3. Patriot - (Lots of things wrong with it, but good Battle Scenes)

It's a pretty good overview of the war, with some pretty cool reenactments of the battles. I really enjoyed it and would recommend it
